I have a timing issue with b8a6f9337229 (and quite possibly other revisons): isabelle build takes 22 secs before it says "Running ...". Since creating latex documents requires many, many iterations, this is extremely painful. My setup is the following:
session A = HOL + sessions "HOL-Library" theories 10 theories either local or in ~~/src/HOL session B = A + theories ... document_files ... None of my files are part of a Mercurial repository. I start with building A: isabelle build -v -d . A It takes 6 secs until the build of A actually starts. From now on I will always build B. I start with an almost empty B: 0 theories and no document_files section. It takes 6 secs before it starts the run. Now I add a document_files section with 4 small (less than 3k each) tex files. It takes 8 secs before it starts the run. Now I add 8 pdf files of 70k each. It takes 15 secs before it starts the run. Now I add 10 theories that only import files that are part of session A. It takes 22 secs before it starts the run. All of this is linear: the more files I add, the longer it takes. In Isabelle2016-1 it took 2 secs. I have intentionally not included anything from the AFP. However, importing an AFP session does not seem to make matters worse (although adding -d '$AFP' to isabelle jedit does add 20 secs startup time.) What am I doing wrong? How can I speed things up? Thanks Tobia
